Subject: [PATCH] `assert_equal`: fix `clippy::default_numeric_fallback`

Type of `i` defaults to `i32` when `usize` should be used.
It's only a problem if this function is called with two iterators longer than `i32::MAX`. It seems unlikely to me but who knows?
`i32` should not be the default integer type in the library. `usize` would have more sense so I add the lint as warning (for the library only, it's okay in tests and benchmarks).
